Sponge city road rainwater integrated recycling treatment system

Abstract

The invention discloses a sponge city road rainwater integrated recycling treatment system, which comprises a rainwater collection unit, a rainwater treatment unit and a rainwater utilization unit which are connected in turn. The rainwater treatment unit comprises an initial rainwater discarding device and a membrane biological reaction tank, and the membrane biological reaction tank is communicated with a water storage module. An initial rainwater discarding device includes a discarding pool, The inlet of the discarding pool is provided with a permeable partition plate and a floating plate, and the permeable partition plate and the floating plate are connected into an I-shaped structure. The one side of the discarding pool is provided with an opening, and the opening is provided with a baffle plate which is connected with the municipal sewage pipe network. Inductors are arranged on the inner walls of the permeable partition plate, the floating plate, the baffle plate and the discarding pool inlet. The rainwater utilization unit comprises a water storage tank communicated with a water storage module, wherein the water storage tank is provided with a water pump connected with a spraying control device on the ground, a moisture sensor connected with the spraying control device is arranged in the soil on the upper part of the water storage tank, and the water storage tank is alsocommunicated with the municipal pipe network through a pipe valve.

Description

technical field [0001] The invention belongs to the technical field of sponge city construction and rainwater resource utilization, and in particular relates to a sponge city road rainwater integrated circulation treatment system. Background technique [0002] my country is a country seriously short of water resources. According to statistics, more than 50% of the more than 600 cities in the country are short of water, and nearly 20% of the cities are seriously short of water. In recent years, with the rapid development of urbanization, the area of ​​urban green space has gradually decreased, and most of the green spaces, wetlands, ditches and other areas that originally had the function of water conservation have evolved into hardened ground. As a result, cities can only rely on municipal management in the face of heavy rainfall. Network drainage, resulting in frequent waterlogging disasters and serious runoff pollution; but after the heavy rain, it fell into the predicamen...

Problems solved by technology

[0004] Chinese patent application 201610605947.4 proposes a sponge city road system and a method for collecting and utilizing rainwater. The main technical solution is that the rainwater on the motorway passes through the perforated station stone and then enters the grit chamber. The rainwater from the sunken green belt flows into the overflow well, and the water in the overflow well enters the water storage tank for storage after passing through the filter wall; when the water in the overflow well overflows the overflow port, the water flows into the municipal In the drainage pipe of the pipe network, but the disadvantage of this method is that it does not consider the problems of the initial rainwater abandonment, road permeable pavement, rainwater counterflow, etc. The practicability is not particularly good, and it is easy to cause secondary pollution to the environment
